default routes question or any way to do the rebundant

[ann kok <annkok2001 () yahoo com>]

Hi 

ls it possible to have 2 default routes?
or how can I do the rebundant when the route is still
working either eth1 or eth2 down?

Router2
   192.168.0.2/20 eth1
   192.168.0.18/20 eth2
   10.0.0.1 eth3


ip route 0.0.0.0/0 192.168.0.1 
ip route 0.0.0.0/0 192.168.0.17

or 

ip route 0.0.0.0/0 192.168.0.1 
ip route 0.0.0.0/0 192.168.0.17 2


Router1 
  192.168.0.1 eth
  192.168.0.17 eth2
  172.16.0.1 eth3

host1 10.0.0.2 connects R2 couldn't ping host2
172.16.0.2 connects R1 when the link 192.168.0.1 is
down


host1-----R1--Switch---R2-----host2
            --Switch---

i am using freebsd router


Thank you for your help
